Justem said on Sunday it recorded 48.3 billion won in revenue and 4.6 billion won in operating profit in 2025. Revenue rose 24.7 percent and operating profit jumped 200.6 percent from a year earlier, returning the company to profit. Net profit came to 3.6 billion won, up 264.3 percent. Revenue was the highest since the company was founded.

It said expanded investment in AI semiconductors and a sharp rise in memory demand drove the improvement. Justem said it has continued to win orders for humidity-control solutions from global semiconductor companies. It also completed a supply system to apply its systems across three global semiconductor companies, expanding order volume. That led to a more advanced revenue structure centered on high value-added products.

It supplied humidity-control solutions to SK Hynix and Micron at the largest scale in its history. It also supplied Samsung Electronics with its second-generation humidity-control system, JFS (Jet Flow Straightener), an airflow-control solution, on a large scale in a short period.

The company said it expects the growth trend to continue this year. It cited deepening supply shortages across HBM (high-bandwidth memory), server DRAM and advanced foundry processes. Justem said it expects demand for humidity-control solutions to expand as the importance of stabilising yields and securing mass production comes into focus. It expects its first-generation N2 Purge System and second-generation JFS to drive earnings growth in 2026 as well.

The company is also preparing to launch its next-generation humidity-control solution, JDS (Justem Dry System). It said the product merges the functions of JFS and its third-generation solution, JDM (Justem Dry Module), to maximise synergy. The display business is also progressing smoothly. Justem said it is continuing to secure new customers in Greater China following supplies to major display companies in South Korea.

Lee Mi-ae (이미애), vice president of the management planning division, said, "As yield and mass-production stability are key issues in the global semiconductor market, demand for humidity-control solutions to improve yields is bound to grow." She added, "In the flow of the supercycle, we expect continued expansion of orders in 2026 as well."
